Description

CONTROLLING THE ANGULAR EXTENT OF AUTOSTEREOSCOPIC VIEWING ZONES}

This application claims the priority of US Patent Provisional Serial No. 60 / 688,100, filed June 7, 2005, entitled "Controlling the Angular Extent of Autostereoscopic Viewing Zones" and inventor Lenny Lipton et al. The entirety is incorporated by reference.

This design relates to the projection of an autostereoscopic image, and more particularly, to generating a strong depth effect on an autostereoscopic image received from an autostereoscopic display over a wide viewing distance from the display. will be.

The autostereoscopic display is somewhat optically compatible with the lenticular sheet (and in some cases, the lenticular sheet) as an optional device to enable viewing of stereoscopic images without the use of individual selection devices (glasses) worn by the observer. Raster barriers are used. The technical term used for these types of displays is "panoramagram" or sometimes "parallax panoramagram" when more than two views are provided.

As it described by Okoshi 3-D imaging technology [Three Dimensional Imaging Techniques (Academic Press NY, 1976)], a plurality of perspective views the panorama grams have been combined to be imaged by the lens sheet. In a lenticular (or raster barrier) stereoscopic display, one object of interest is head movement or user position relative to the display. Head movement in the horizontal direction allows the observer to see a change in perspective within the viewing zone, which is the spatial region for the display where the images on the display are viewed. Perspective views repeat in adjacent viewing zones as the observer transitions from zone to zone, such as moving between viewing zones. That is, changing perspectives occurring in the primary viewing zone repeat in the secondary zone and other surrounding zones as the observer moves laterally. These secondary, tertiary and n-th order viewing zones have similar image quality as the primary zone. Beyond the nth order zone, relative image quality is likely to degrade significantly. The performance is symmetrical with respect to the primary zone and the angle range of the zones is similar. The transition from zone to zone is usually simple in that all zones throughout provide the maximum angular range of the viewable image.

When selection occurs in the plane of the screen, many perspective views are required to provide a viewing area with a wide angular range. For displays where only two views, sometimes called parallax stereograms, are provided, some head movement is acceptable and the viewer's position is constrained. This limitation of movement is inconvenient and undesirable.

The electronic display panoramagram can be adjusted to function well in two different viewing situations. The first is a range of walk-up viewing distances, for example, 4 to 15 feet away from the display, and also, for example, from distances consistent with the airport environment where the display is mounted high and viewed from 15 feet or more. It is the range of view distance. Currently, no commercially available panoramagrams perform well in both scenarios.

Thus, previously available designs suffer from variations and problems in viewer position relative to the display. It is desirable to provide a design that enhances or optimizes the autostereoscopic display of an image by allowing the viewer to be positioned at various distances from the display.

According to one aspect of the present design, a method and system are provided that provide the ability to vary the angular range of a panoramicgram viewing area received from a display having a first amount of data columns associated with each other. This design includes providing a first data column having a baseline number of views associated with each other, the first data column being provided to one or more lenticules in the lens sheet associated with the display. The design further includes changing the first amount of data columns to a second amount of data columns provided in the one or more lenticules. The second amount of data column includes more views than the baseline number of views. Employing a second amount of data columns when constructing an autostereoscopic image provides a display with a relatively clear view of the autostereoscopic image over a particular viewing distance.

These and other advantages of the present invention will become apparent to those skilled in the art from the following detailed description of the invention and the accompanying drawings.

1B is a perspective view of a Winneck type lenticular array.

FIG. 3B is a schematic diagram illustrating a viewing space of the optical design of FIG. 3A.

4 is a general flow diagram illustrating the operation of the present design.

This design utilizes refractive semicylindrical lenticules of the types shown in FIGS. 1A and 1B. In this configuration, two related types of lens sheets are available, both having similar properties. Lenticular sheets or raster barriers enable viewing of stereoscopic images and are optically compatible without the use of individual selection devices (glasses) worn by the observer. The teachings of the present invention apply to both types of selection devices.

In order to see an autostereoscopic image, the observer must be within some distance from the display and not too far or too close. If the distance is too far, the observer will see the views with a reduced perspective difference, as shown in FIGS. 2B and 3B and described more fully below. The intensity of the stereoscopic depth effect is proportional to the interaxial separation between camera positions, the camera being in the visual world or computer universe. Perspective views within a particular zone or area are easy to fan out spatially, and the observed stereoscopic depth effect is described by a particular stereopair seen by the observer. When limited from a distance far enough from the display, there is no perspective difference since the observer sees only one perspective.

The design solves this problem and provides a software change that produces a stereoscopic depth effect where the observer can be positioned over a wide viewing distance. The display can be useful, for example, for point-of-sale applications of 4 to 15 feet. In some circumstances the same display preferably functions at, for example, 15 to 30 feet over a different range of viewing distances and still provides a stereoscopic viewing experience. The angular range of the viewing zone can be reduced to provide sufficient perspective difference for stereoscopic viewing. In this way, the observer's eye sees the perspective views that are generated or captured from the larger interaxial gap. Although the angular range of the zone is reduced, the width of the viewing zone can still be large because the distance from the display is also increased to achieve a good stereoscopic effect from a greater distance. At a given angle, the larger the viewing distance, the larger the width of the viewing area.

This design maintains the horizontal width of the viewing zone, not the angular range, when the observer is further away from a given distance. That is, the depth effect is maintained for far viewing as compared to close viewing.

In operation, if the viewer moves left or right from the center of the display, he or she looks at the image columns adjacent to the primary column. Each column contains a complete set of perspective views. The primary columns are located immediately after the relevant lenticules as shown in FIG. 2A. Thus, when the same lenticule is used to view off-axis, it provides imaging for the perspective columns closest to the left or right side of the column, referred to herein as the "primary column." Within the limits, the aspect of the non-primary viewing zone is similar to that of the primary viewing zone.

In addition to the importance of positioning the head horizontally or horizontally, the distance of the observer from the display is also important. If the image is optimized for close-in view, for example, the stereoscopic effect is reduced when the viewer moves further away, which is undesirable.

The angular range of the viewing zone is of fundamental importance in controlling the stereoscopic depth effect. The narrower the viewing area, the deeper the stereoscopic effect. The wider the viewing area, the easier it is for an observer to position himself in order to see high quality stereoscopic images. Since a limited number of perspective views are available, a balance is obtained between the angular range of the viewing area and the depth effect. Although it is desirable to have the widest possible angular range for the viewing area, increasing the angular range of the viewing area reduces the depth effect assuming that the observer is at a constant distance given a limited number of tush views. On the other hand, reducing the angular range of the viewing area increases the depth effect, but limits the area where the stereo image can be seen. An important parameter is not necessarily the angle range of the viewing zone, but the horizontal width of the viewing zone at a given viewing distance.

Control of the angular range of the viewing zone is of significant interest. Typically, the primary viewing zone, either of the primary viewing zones, has a secondary viewing zone and a tertiary viewing zone of somewhat equal angular range, and stereoscopic images may be viewed from other surrounding zones. The angular ranges of the secondary, tertiary and other surrounding viewing zones typically match the angular ranges of the primary viewing zone.

The design is a novel electron panoramagram using a lenticular array (or raster barrier). The design further includes making a software change to the interdigitation process that allows the display monitor to be used at different locations at different distances without changing the lenticular screen.

The term interdigitation, which some authors call interleaving and interzigging (the term used by the StereoGraphics Corp. company), is the process by which multiple perspective views are sampled and then mapped into a single image file. In its simplest form, the left and right images are optically vertically sliced or alternated for juxtaposition behind the lenticular screen, as described in Hess US Pat. No. 1,128,979. In a typical hardcopy optically generated panoramic diagram (where there are many views), each view is sampled and arranged into image stripes after each vertical-going lenticule. This type of lenticular screen is shown in FIG. 1A. The repeating perspective view array of stripes is a column, with one column immediately behind and having the same width as the vertical lenticules. Striping and column descriptions are simple for computer interdigitation. In the case of using the Winnek lens array as shown in FIG. 1B, more complicated mapping may be required as necessary. This design adopts the stripe and column descriptions for FIGS. 2A and 3A portions 202 and 301.

1 shows a lenticular display 101A composed of a semi-cylindrical or corduroy type structure 103. The back side of the lenticular display 101A faces the electronic display 101. Electronic display surface 101 is typically a flat panel display. The pitch of the lenticules 102 may be defined as the width of the lenticules, shown as P lying within the arrows. The boundaries or intersections of the semicylinders are parallel to each other and parallel to the vertical edges of the display 101, where the display typically has a rectangular shape.

FIG. 1B shows a variation on this approach and employs the design of Winnek as shown in US Pat. No. 3,409,351. The intersection boundary of the semicircular cylinders in parallel to each other is not parallel to the vertical edge of the display and is inclined at an angle as shown at point 112. This diagonal-going lens sheet 113 is associated with the flat panel display 101. Without loss of generalization, the techniques shown here apply to standard vertical lenticular arrays, Winnek oblique state arrays, or raster barrier arrays following vertical orientation or Winnek teachings.

FIG. 2A shows the cross section of a single lenticule 201 with the cross section of stripes labeled 1,2,3,4 and associated display image column 202 to represent individual perspective views imaged by the lenticules. Indicates a part. Any number of views may be employed but four are provided for simplicity of explanation. The design of FIG. 2A applies to both vertical lenticules, Winnek diagonal lens sheets, and also raster barrier selection devices, which may be vertical or Winnek diagonal. For simplicity of illustration, the drawings are not drawn to scale. In some cases, exaggeration or simplification is made to facilitate the description.

FIG. 2B shows an electronic display panel 203 covered by lens sheet 208, which is composed of a number of individual lenticular elements given by FIG. 2A. The space in front of the display includes a primary viewing zone 204, the angle range of which is the primary viewing zone.

. This angular range is compared to the primary viewing zone shown in FIG. 3B. The angle range of the primary viewing zone shown in FIG. 2B is approximately twice the size of that of the zone shown in FIG. 3B.

For simplicity of explanation, the secondary, tertiary, and other peripheral viewing zones have the features as described above and are not described herein. The design aspects and optical phenomena described herein apply to these zones and the surrounding zone changes proportionally when the angular range of the primary viewing zone changes. Four perspective views are shown unfolding in the viewing space at point 207, each view corresponding to the perspective views shown by point 202 in FIG. 2A. Since an electronic display with a finite pixel structure is employed, perspective views can be composed of a collection of pixels or sub-pixels. Each view occurs as a few vertical slices that unfold in space. The top view of FIG. 3B shows the sliced region in the form of a slice of pie, labeled 4, 3, 2 and 1, with perspective subsections going from left to right. The change in direction for the subsection occurs because the lenticules 201 optically invert the perspective 202.

Both eyes given by 205 are shown at a greater distance at point 206. The interpupillary distance is equal to the distance to both eyes, given by t. From FIG. 3B, it is necessary to spread the viewing area irregularly to see the stereo view. By way of example, views 2 and 3 are for the observer at point 205. If the observer is far enough away from the distance indicated by point 206, then the right and left eyes cannot see the see difference because the observer's eye is within the range of a single stripe, as indicated by stripe 3 in this case.

Some optimal ranges are for viewing the panoramagram, and as the viewer moves further away from the display 203 with the lens sheet 208, the opportunity to see the stereo pair is reduced. As the observer gets closer to the display, the views that make up the stereopair shown are created with greater interaxial spacing than that given when the observer is far from the display. Thus, being close to the display within range provides a strong stereoscopic effect, and conversely, being far from the display provides a reduced stereoscopic effect. In extreme cases, as can be appreciated with respect to point 206, there is no stereoscopic effect. The wider the zone, the stereoscopic effect is also a function of the angular range of the viewing zone because it perceives that the perspective views given a fixed value t are further away. Conversely, the narrower the region, the deeper the image, since the perspective views shown are captured or captured from a greater distance. The intensity of the stereoscopic effect is a function of the interaxial spacing of the stereo pairs or of the distance between generated or captured images.

The design allows the viewer to see the left and right eyes at a distance from the display, the same views that can be seen when the observer is located at close range.

One approach is to change or replace the lens sheet. Increasing the focal length or focal lengths of the lenticules depends on the angular range of the viewing zone 204.

Makes it possible to narrow). Changing or exchanging lenses is impractical in a real-world situation. The design repeats the perspective view twice as shown by point 301 within each single lenticule within the pitch of the stripe and within the width. In fact, this perspective view iteration processes the display in an interdigitation process as if the lenticular pitch was twice as precise or the width of the lenticular was half the actual physical width. In this embodiment, the image column is the same width as the width or pitch of the lens. Thus, each set of perspective views is repeated twice, so that the perspective views given by 1, 2, 3 and 4 are repeated again as 1, 2, 3 and 4 under each lenticule as shown at point 301. Point 301 is associated with the same lenticule 201 as the lenticule used in FIG. 2A. FIG. 3A shows perspective views or stripes 1,2,3,4,1,2,3,4 indicated by point 301 and occupying the same column width as 1,2,3,4 in FIG. 2A. The shown lenticule 201 is a simple lenticule of the lens sheets described from FIGS. 1A and 1B. For simplicity, the above description uses an iteration of the argument of 2 as an example, but other large arguments may also be used.

/ 2) is now half of the horizontal angle range of the primary viewing zone shown in FIG. 2B. Similarly, the secondary and tertiary zones are also reduced in angular range. For the electronic display 203 with the lens sheet 208 (same as that shown in FIG. 2B), the see-through stripe sequence repeats twice under a single lenticule. Therefore, the patterns that were 1,2,3,4 are repeated and the number of columns under the lenticule is doubled, so that the patterns under the lenticules become 1,2,3,4,1,2,3,4.

The observer 305 located at the same distance as shown in FIG. 2B at point 206 has the ability to see perspective views at point 306 with a larger interaxial gap than is currently available in FIG. 2B. In the example shown in FIG. 3B, compared to FIG. 2B, an observer with an interpupillary interval fixed at t currently sees each of views 3 and 2 rather than simply view 3. This brings awareness of the current stereoscopic view. This particular example is an extreme case where improvements are made from nonstereoscopic views to stereoscopic views. The same effect applies to the observer who sees the distant perspective views. For example, if an observer sees views 3 and 2 at a given distance, the observer sees views 4 and 1 as a result of his viewing a deeper stereoscopic image, with a decrease in the angular range of the region as taught here. Can be seen.

The same principle is valid for secondary, tertiary and other surrounding viewing areas. The design may include repeating the pattern three times (eg, 1,2,3,4,1,2,3,4,1,2,3,4) or in fact repeating n times. . The ability to repeat the pattern of perspective views and reduce the angular range of the viewing area, thus increasing the stereoscopic effect is limited only by the resolution of the display. Repeating the pattern allows the viewer to see a stronger stereoscopic effect farther from the display. Observers relatively far from the display cause a decrease in resolution, making the image hardly visible.

The description provides for the use of these four views, and in practice there is no such limitation. Any number of views may be employed, including nine, sixteen, or other numbers of views. Furthermore, while the case of articulated or lenticular displays is described herein, this procedure also applies to raster barriers. In addition, while the present design is described by showing what occurs with individual lenticules, one lenticule simply represents activities under the entire lens sheet that may include thousands of lenticules.

The design may be implemented in any of a plurality of displays and / or devices including, but not limited to, an Apple Cinema Monitor with a diagonal 30 inch display screen with a resolution of 2560 by 1600 pixels. The resolution of this monitor is the size of the current standard, allowing pixels under lenticules to repeat the perspective pattern. In this configuration, a relatively thin glass substrate can be employed, such as on the order of 0.090 inches, and lenticules with a pitch on the order of 0.80 mm can be cast over the glass substrate. Proprietary interdigitation algorithms such as Interzig by StereoGraphics Corporation, or other interdigitation algorithms may be employed. Interzig considers the optics of a Winnek type lens sheet as described above.

With this kind of slanted arrangement, the views are not only mapped to rows containing color and perspective stripes that run parallel to the horizontal edge of the display, but also the views are vertically or substantially diagonally within the column. Are arranged. Multiple view perspective image groups may be employed, such as nine perspective view image groups. For a typical vertical panoramic diagram, nine stripes in a column are provided in a design where the stripes travel along a row (going from 1 to 9) in a column just below a single lenticule.

In a Winnek arrangement, an image group occupies several rows under a lenticule to which the principles described above still apply. Although this description employs a conventional panoramic diagram with vertical lenticular boundaries for teaching purposes, it may be necessary to address some additional complexity depending on the application. Whether views are formed by perspectives that are progressively arranged in a row on a column-by-column basis under each lenticular and the column is interdigitated in stripes under the row, or in a more complex manner where perspective views are required by the Winnek array. Whether arranged, the overall principle for this design provides a plurality of perspective views, where a limited number of perspective views have already been provided. For a flat panel display, the pixels are composed of clusters of red, green and blue subpixels. This design is more complex because interdigitation algorithms, such as the Interzig mapping algorithm, operate on values based on subpixel manifestations.

One implementation of this design uses an array of pixels per lenticular (P / L) of approximately 3.204. This gives nine views in the column under the lenticule. Changing the P / L ratio to approximately 1.602 provides 18 views under each lenticle with sufficient patterns of 1 ... 9, 1 ... 9. The viewing zone was divided in half in the angular range, and the depth effect was greatly enhanced when viewed from a distance. In particular, at a P / L of approximately 3.204, a good stereoscopic image can be viewed within the viewing zone in an angular range of about 5 to 15 feet to 10 degrees. In addition to the primary zone, good secondary, tertiary zones and two additional exterior zones provide a total of seven good viewing zones for proper viewing. Dividing P / L in half by approximately 1.602 can provide a good stereo view even greater than 15 feet. Using this design, the number of good viewing zones is increased.

Despite the fact that the range of the view of the zone is divided in half, the horizontal range of acceptable head movements within the head box, or new zone, is large, allowing easy viewing. The observer can imagine a viewing area that forms an isosceles triangle with vertices close to the plane of the display. The viewing area width measured by the line included in the plane parallel to the surface of the display and parallel to the horizontal edge of the display is approximately proportional to the distance from the screen. If the angular range of the zone is reduced by half, doubling the viewing distance can result in approximately the same zone width. In this case, the same perspective stripes can be observed (depending on the position from side to side or side to side within the zone) even when the viewer is at a greater distance. Thus, the stereoscopic depth effect is maintained over the farther overall distance. Despite the fact that the resolution of an image under lenticular is divided in half, images using this design tend to be relatively sharp. An observer who is located quite far from the display can compensate for the reduction in resolution determined by the number of pixels available for image formation.

In addition to the extension of the ability to perceive depth from greater distances, the design provided herein has the effect that the reduction in the viewing zone angle range provides a stereo pair for eyes with larger interaxial spacing than before the zone range reduction. As such, it can also be used to increase the depth effect within the normal viewing distance range.

Thus, changing the interdigitation constants in software can provide a repeating pattern of perspective views under each lenticule of the lens sheet, whereby the viewer can, for example, of its original distance from the display. At twice the distance, the angle of view can be divided in half with the accompanying increase in stereoscopic effect. In this way, the same autostereoscopic display that is pleasantly viewed from a short distance can be formed to have an increased stereoscopic depth effect from a long distance.

The general design reflected here is shown in FIG. 4. In general, the software is not required, but can set a baseline profile at point 401, which represents the number of views provided just below a single lenticule. In one of the examples described above, views 1,2,3,4 are provided. Point 402 is doubled or otherwise multiplied by the number of views by an argument, for example, views 1,2,3,4,1,2,3,4,1,2,3,4 are the same. As it would be just below the lenticule, it represents increasing the number of views provided just below the lenticule. The values or views so provided are then applied to the interdigitation process or program at point 403. A general purpose processor or computing device may set the number of views provided beneath each lenticule based on the baseline, the expected baseline, or the number of views generally understood, and calculate the increased number of views to be transmitted. have. The processor can then pass the number of views per lenticular and the number of actual views to the interdigitation program, or enlist a memory device or other suitable device or circuitry to calculate the number of views computed by the StereoGraphics Corporation company. It may be provided to an interdigitation processing apparatus or module for interdigitation or interdigitation in the case of proprietary software.

Another way to look at such a design is to provide the ability to change the angular range of the panoramicgram viewing area that is received from the display having the first positive data columns with which the design is related. The design provides a first data column having a baseline number of views that are related to each other. The first data column is provided to one or more lenticules in the lens sheet associated with the display. The design further includes providing a second amount of data column changed from the first amount of data column to the one or more lenticules. The second amount of data column includes more views than the baseline number of views. Employing a second amount of data columns in constructing an autostereoscopic image provides a display with a relatively clear view of the autostereoscopic image for a particular viewing distance.
